Abstract (en)

[origin: WO2020025548A1] The invention relates to a preform made of polyester for producing a plastic container in a blow moulding process which comprises a tube-like preform body which is closed at its one longitudinal end and at its other longitudinal end has a neck section provided with an opening for pouring. The polyester is based substantially on furandicarboxylic acid and diols, wherein the diols are derived partly from the group of spiro compounds and partly from the group of conventional diols.
